Patented Dec. 30, 1930 UNITED STATES WALTER F. CLAY, F TEXARKANA, TEXASTOOL Application filed July 21,

The object of this invention is the provision of a combination tooldesigned for use by automobile repairmen, and the primary object is theprovision of a tool of this character which may be employed for cuttingbolts, removing battery cables from their posts, riveting brake liningsand removing generator bearings and gears, etc.

An important object of the invention is a novel construction of framesthrough which is guided a reversible rack bar that has both of its edgestoothed, the said teeth being engaged by teeth on the segmental ends ofhandles which are, pivoted between the sides of the frame, and whereinthe frame is of such construction as to have removably pivoted theretodifferent types of jaws which have link connections with the rack bar,as well as an anvil jaw which is designed to cooperate with a punch onone end of the rack bar, the said rack bar being reversibly arranged inthe frame.

To the attainment of the foregoing and other objects which will presentthemselves as the nature of the invention is better understood, theimprovement also resides in certain other novel features ofconstruction, combination and operative association of parts,satisfactory embodiments of which are disclosed by the drawings.

In the drawings:

Figure 1 is a side elevation of the improvement with parts broken away.

Figure 2 is a perspective view of the jaw employed and also disclosingthe head for clinching a rivet which may be arranged on the jaw.

Inthe showing the frame of my improvement comprises two. side plates 1between which there is arranged spacer or filler blocks 2, the sideplates being secured to the filler blocks by removable means 3. Asdisclosed by the drawings thefiller plates are arranged in'spaced pairsadjacent to the opposite ends of the frame, and the confronting pairs ofsuch plates are spaced equidistantly away from each other. The sidemembers of the 7 frame, at the outer portion are formed withsubstantially U-shaped or yoke-like extensions. These yoke-likeextensions are formed 1928. Serial No 294,474.

by cutting away the central portions of the plates 1, beyond the outerfiller blocks 2. For distinction the connecting elements for the arms ofthe yoke-like extensions are indicated by the numeral t. I

The operating handles are indicated by the numeral 5, each of whichmerges into a segmental head 6 which is toothed, as at 7, and theseheads are pivoted, as at 8, between the sides of the frame, and likewisebetween the spaced pairs of spacer blocks 2. Arranged for slidablemovement through the frame, and guided in such movement by a slightcontact with the blocks 2 there is a reversible rack bar 9. This rackbar has both of its edges toothed, as at 10, and these teeth aredesigned for engagement by the teeth on the segmental heads 6 of theactuating handles 5. The rack bar 9 has its sides or edges inwardlyinclined, as at 11, to one end of the said rack bar, and removably fixedin this end of the rack bar there is a punch 12.

The slidable rack 9, adjacent to its second or opposite end is providedwith a pair of oppositely disposed spaced openings 13.

, In Figure 1 an anvil jaw, illustrated by the perspective view inFigure 2 of the drawings, is employed. The jaw includes a reduced shank27 which rests on one of the outer spacer blocks 2, the said shankhaving an opening 27 therethrough to register with the pivot openings inthe yoke that receive therethrough one of the removable pivots 20. Thewidened outer portion of the jaw affords inner shoulders 28 which aredesigned to rest on the outer edges of the yoke, and this widenedportion has its inner face concaved and from thence is formed with aright angle extension 29 that has an opening 30 therethrough in a linewith the punch 12. The outer portion 29 of the j aws 28 affords an anvilfor the punch as will, it is thought, be readily understood. The tool,when the parts are thus arranged is designed for punching holes throughthin metal sheets, and driving out drift pins and for other purposes.

The construction and advantages of my improvement will, it is thought,be understood and appreciated so that further detailed description isnot thought necessary. Obvious- 21 a i I j r 1,787,358

1y I do not Wish to be restricted to the precise details herein setforth and, therefore, hold *myself entitled to make such changestherefrom as fairly fall within the scope of what 5 I claim.

' Having described the invention, 1 claim: V In a tool for the purposeset forth, a frame comprising two spacedv plates, blocks a1;- ranged inspaced pairs between and renio'vably p 10 secured to the plates, each ofsaid plates having its central portion cutaway beyond the;

outer blocks to provide the said plateswith yoke-like extensions, a rackhaving both of its u edges toothed, slidable between the'blocks 15 andyoke, a pair of handles eachhaving'a seg 1 l1 mental head which istoothed, and which are pivoted between the sides of the, frame, toengage with the teet'lio'f the rack, a punch on one end of the rack, ajaw having a reduced r-9 shank received through the yolre'a-nd restingupon one of the outer spacer blocks, removable means securing theshankto theyolie, f said jaw havingan outer widened portion which afiordsinner shoulders that rest on 25 the outer edges of the yoke, thesaid'wider portion having its inner face concavedl and formed fromthence with a right angular eX tension that has an opening therethroughin a'line with the punch r In testimony whereof I my signature.
